title: Mutagenicity and toxicity of aflatoxin precursors.
abstract: The Salmonella/microsome test and the chick embryo test were used to determine the mutagenicity and toxicity of five aflatoxin B1 precursors. A definite pattern emerges: the nearer the B1 an intermediate appears in the biosynthetic pathway, the more potent is its mutagenicity and toxicity.
